When major portions of the country is in other than 70 MPH wind
zones, it would make sense to do at least sample calculations
for 80 and 100 MPH (or 110 MPH) wind zones. Manufacturers of
guyed and freestanding towers (including Trylon on your web site)
provide 70, 80 and 100 MPH loading information standard.

I was ready to buy, but the vendor/manufacturer was not willing to
provide the basic information necessary for me to make an INFORMED
purchasing/product selection decision ... damn straight I'm insulted!
Most intelligent people confirm a product is suitable for its
intended use and environment before they make a significant purchase
commitment. Part of the decision requires careful evaluation of the
manufacturer's specifications ... the customer should not have to
pay just to see the specifications.
I simply asked for maximum load ratings (square feet of projected
area) extended and retracted for two or three candidate towers at
100 MPH - which is what the charts show for this county (it's not
as if I asked for a set of wet stamp drawings for each tower!).
